fix: lookup action roles from the params and simplify stuff

[bassgeta]

Description

This one was quite something to wrap one's head around 😅
Basically I've unified how we get roles from the action. We now display a difference between the user's assigned roles and historic roles (if they don't exist, then their current roles in the colony).
Additionally, we determine that an action is removing roles if all the values in the roles array are false, which is true in regards to how we call the contract.
For example, if the user has the roles [2, 5 ,6] and we want to update their roles to [2, 6], we would call the contract with new roles and those override the old ones.

Testing

I am sorry, this one's quite a doozy, but I'll try to make it as concise as possible.

1. Run your dev env, the create data script, install the Voting Reputation extension and the Multi-sig extension. Give leela the Multi-Sig Owner role in General
2. Give amy the Payer permission bundle in Andromeda via Permissions and verify it shows up and you can redo it
   
   
   
3. Give fry the Payer permissions in Andromeda via Multi-sig. Make sure everything is correct and finalize the action so the roles get applied.
   
   
4. Give amy the Admin permission bundle in Andromeda via a voting reputation motion. Verify it shows up as the admin bundle in the UI. No need to finalize the motionat all 👍
   
5. Give fry custom roles by removing the Administration role via permissions from the custom toggle form. NOTE: this is a bit funky with the titles, on master we show this action as Removing permissions but motions show Add custom permissions 🤷
   
   
6. Completely remove fry's roles in Andromeda via Multi-Sig.
   
   

Whew alright we made it to the end of testing all of this via Permissions, so now let's just do the same for Multi-Sig roles 🫠

1. Give amy the Payer Multi-Sig permission bundle in Ascendant via Permissions
   
   
2. Give fry the Payer Multi-Sig permissions in Ascendant via Multi-sig. Make sure everything is correct and finalize the action so the roles get applied.
   
3. Give amy custom permissions and toggle the Architecture role by hand in Ascendant via a voting reputation motion. Verify it shows up as the admin bundle in the UI. No need to finalize the motionat all 👍
   
   
4. Remove the Administration Multi-Sig role in Ascendant from fry via permissions and make sure it shows up correctly.
   
   
5. Completely remove fry's Multi-Sig roles in Ascendant via a voting reputation motion and make sure everything shows up as expected
   

Last but not least, make sure that the Redo action popup in the activity feed shows up for actions which are not removing permissions. My dev env just crashed when doing this step 🫠

Diffs

Changes 🏗

• The SetUserRoles completed action view now contains some more comments on what's being done code-wise
• Simplified the logic for displaying a user's roles a bit.
• Note that the activity feed's title still assumes we are removing roles if the passed roles are all false, which is not necessarily true 🤷
